TO ALL WHOM IT MAY CONCERN: Be it known that l, SHERMNE. ANTHONY, of Stillwater, in the county of Saratoga, and State of New York; have invented a new and improved Shingle Machine; and I do hereby declaro that the following is av full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a side sectional viewiof'my invention, taken in therline x x, tig. 2.

Figure 2, a plan or top view of the same.

Figure 3, a transverse vertical section of thel same, taken in the line 1/ y, figs. 1 and 2.`

Similar letters of reference indicate like parts.

This invention relates to a new and improved shingle machine, of that class i-n-which a circular saw is used for cutting the shingles from the bolt; .and it consists of a series of 'disconnected bolt-carriages, arranged to work in suitable guides, and in such armanner as .to form, without hinges, linksfor any connection whatever, an endless chain of carriages. The invention also consists in au improved mechanism for clogging and undogging the bolts, all arranged substantially as hereinafter fullyv shownand described.

A A represent the two sides of" the framing of the machine, which may be of cast iron, and having semicircular ends. The inner surfaces of these side pieces are cast with a groove or recess, `.anali around, near their edges, (see fig. 3,) and in these grooves friction-rollers l, at the ends of bolt-carriages B, are fitted and allowed to wcrkfreely.` The bolt-carriages B are of rectangular form, of cast iron, and they are itted between the side pieces A A'of the'framing, in contact with eachother, so as to form an endless chain of carriages all around the framing, and without being connectedby hinges or joints of any kind. This endless chain of carriages is moved by means of teeth c, on disks or wheels dal, on a shaft, in one end of the framing, the teeth of the two disks or wheels acting against lugs or projections e, at each end of the carriages; audit will bel seen that if one carriage be moved the Whole will be moved. By this arrangement I avoid the use of hinges or joints for connecting the carriages, thereby saving considerable in the manufacture of the machine, as well as avoiding friction. D is a circular saw ,`plaoed on the upper end of a vertical shaft, E,in the machine, the saw being directly underneath the upper part of the endless chain' of carriages. The carriages-B are rectangular frames, each being provided with a sliding-dog, F, serrated or toothed at its lowerpart, and Aprovidt-id at its upper partwith a'horizontal arm, j', which is fitted and allowed Ato work orv freely move in one of the end pieces of the carriages B, thel outer lends of ther armsf being turnedlupward to form a lip', g, to catch under a diagonal flange, h, on a plate, G, attached to the upper part of the framing.A The lips g of the armsfpass behind this ange h as the endless chain of fcarriages is moved, and the dogs F are thereby drawn back out of the ends'o'f the bolts, the latter being held or prevented from-being drawn back out of the bolt by means of a xed plate, z', which pas-ses through the. dogs F.' H is a screw, which is {itt-ed vertically in a.nut or female thread in the ends of the carriages in which the armsfwork. The screws have 'T-headsj on them, and the plate Gr has an upright pin, c,`upon it, and also a curved platc,'l, attached. The screws H are for the purpose of holding the dogs F in the bolts or preventing them from moving casually, said .screws acting or pressing upon the arms f, and to` admit 'ofthe dogs F being drawn ou't from the ends of4 the bolts, as described. The screws are turned by one end ofthe heads 7' coming` in contact with .theuprightpin lo, on the plate Gr, and after the dogs are drawn back to free the bolts, andthe latter drop upon the lifting-bed O, hereinafter described, the dogs F are forced into the ends of the bolts, in consquence' of thelipsg` of the armsf coming in contact with a spring, K, on plate G, thescr'ews H being turned down to. press upon the armsfby theplate I, against which the heads j come in contact. The dogs L, at the opposite ends ofthe bolt-carriages, are xed or stationary, and provided'with serrated ortoothed edges. The bolts are freed fromthese dogs L by means of sliding-bars M, which have arms Z attached, the latter passing through the end pieces of' the carriages and turned upward at their outer ends to form lips which come in contact with the bevelled'end of a plate, N, on

the framing, said bevellcd end forcing the bars M forward so as to shovel the ends of the bolts free from the dogs L as the dogs F at thc other cnds'of the bolts arc drawn out from them. The bolts, which are shown inA red inligs. 1 and 3, drop upon a tilting-bed, O, when freed from the dogs, and this tilting-bed causes the shingles to be saw'ed from the bolt in taper form, the bolts being undogged and set'by the bed O previous to'coming in contact with the saw. The bed O is simply a rectangular frame, fitted on a centi-a1 shaft,m, and resting at one end on a toothed Wheel, the shaft n* of vwhich has a 4circular disk, P, upon it, provided 'with kteeth 0.', This dis-k P- is rotated by 'the endless chain of vcarriages as they are moved along, and the toothed wheel n'raises and inclines the bed in one position hy its teeth catching o'r noting against a rod, o, projecting from` said bed; the hed being inclined inthe opposite direction when the rod o* drops between the teeth of the wheel n.

tooth of the wheel n comes under and acts 'pon the rod o* at every alternate inov'ement of the wheel n, the

rod o* dropping between the teeth at the intermediate movements. The bed O may be inale to tilt at a greater or less angle by adjusting the wheel non its shaftu* nearer to or further from the-shaft m of the 'bed O. The tilting. ofjthe bed O, solthatit will be inclinedv 'consecutively in opposite directions, causesl the shingles to -be sawed in proper taper, form. i

'I do not claim the tilting-bed .0, for that is anl oldaud `well-known' device; butI do claim as new, and desire to secure by Letters. Patentv Y Ii. The disconnected bolt-carriages B, with projections e, operating with the toothed wheelsd, substantially illh'e'operating'of the sliding-dogs'through the medium of-'the T 'headed screws vH, flanged spring plate G, pin 7c, armf, and lip g, substantially as describerlfor the purpose specified. f

3. The xed or stationary dogs L, in connection with the sliding-liars M and the plates N, on the framing,

'having bevelled or diagonal 'cnds,' substantially as shown and 'described'.

4.' The fixed plate z', in combination ivttli the slotted dogs F, substantially as and for the purpose specified.`
